它说在我的数组中我已经浏览了索引。我的节目是5个玩家（5个索引）玩的数字猜测游戏。我使用数组来创建对象和播放器类。 我已经到了一个残端，我的程序在第二轮或第三轮比赛中崩溃了。我注意到在第二轮中，索引没有循环属性：循环在第一个循环中计算索引1到5，然后在第二个循环中计数2到5，然后如果我甚至到达循环的第3轮，所有的索引都被洗牌，意思是我不能从1到5。
当每个玩家得到3个猜测时，使用这3个猜测和你的游戏。我已经为播放器创建了一个对象数组，创建了一个比前一个更小的临时数组并引用它来实现当前数组。
我在代码中查看了我的引用，发现尽可能多的代码，我找不到导致我的System.IndexOutOfRangeException的错误。这是由我的猜谜游戏课引起的。

答案 0 :(得分：1)
我在nPlayer长度范围内而不是0-4。
public Player[] getWinner(Player[] nPlayers)
{
int maxScore = 0; //edit
Player[] winningPlayers;
winningPlayers = new Player[5];
for (int i = 0; i < nPlayers.Length; i++)
{
if (nPlayers[i].wins >= maxScore)
{
winningPlayers[i].wins = nPlayers[i].getWins();
winningPlayers[i].name = nPlayers[i].getName();
}
}
return winningPlayers;
}
答案 1 :(得分：0)
这意味着您正在尝试访问大于数组的索引。在该行：
while(playedThisRound[index] == false)
在使用索引之前，你没有检查边界，你的崩溃可能就在那里。
答案 2 :(得分：0)
这意味着您正在尝试访问索引高于数组限制的数组中的项目。
